Key Sensor | KEY + SHIFT ( with First Modifier )
The keyboard sensors allow to sense up to three keys being pressed at the same time.

It is the same behavior as three keyboard sensor's connected to a single AND controller.

There are some things to know about:
- Keyboards can deal with 3 pressed keys -> but more keys might not sensed (this is an hardware/OS issue)
- Keyboard sensors sensing one of the (already sensed) keys will still measure the single key press. It will not automatically ignore the single key because a modifier of another keyboard sensor is pressed.

Exclusive events

When you want to deal with  +  and  differently you need to describe it explicitly:


 AND 
 AND not 


The first condition can be sensed with the modifiers as you do already. Alternative you can use two keyboard sensors with AND.

The second expression requires two keyboard sensors:

-> Keyboard sensor sense 

-> Keyboard sensor sense  [inverted]

combined with AND



or 

-> Keyboard sensor "A" sense 

-> Keyboard sensor "Shift" sense  

(both positive)

combined with expression controller: "A and not Shift"

The last option can be used to reduce the number of involved sensors:
